What is a pop-up city, and what does it actually look like on the ground?

In Episode 82 of the Charter Cities Podcast, Mark Lutter speaks with David Chitta and Michelle Made about Zanzalu, a three-week co-living and co-working pop-up city hosted in Fumba Town, Zanzibar.

They unpack what a pop-up city actually is and what makes the experience unique: shared breakfasts, spontaneous workshops, game nights, student programming, residencies, and the kinds of relationships that continue long after the event ends.

The conversation also explores why Zanzibar and Fumba Town are a natural setting for a pop-up city, what kinds of people tend to attend, and how Zanzalu is evolving in 2026. This year’s edition includes the Zanzalu Idea Zone in partnership with FuTopia, an art residency on Swahili futurism, and the Vanguard residency for emerging African leaders and thinkers.

If you’ve been curious about Zanzalu, pop-up cities, or new models for building community and collaboration, this episode offers a behind-the-scenes look at what Zanzalu is, who it’s for, and why it keeps people coming back.

Africa’s development story is often framed through crisis or pessimism. Joe Studwell offers a different perspective. In this conversation, Studwell explains why Africa’s economic transformation is only beginning. Unlike the post-independence era, today’s Africa has the population density, urban concentration, and educational foundation necessary for sustained development.

Building on themes from How Asia Works, Studwell outlines a historical development pathway shared by successful economies: agricultural productivity, manufacturing expansion, and disciplined financial systems.

The discussion explores:

1. Why demographics and literacy change Africa’s economic prospects
2. Lessons from Mauritius, Rwanda, Ethiopia, and Botswana
3. The role of cities in state capacity and revenue generation
4. Manufacturing as the engine of productivity growth
5. Energy costs, industrial policy, and governance challenges
6. Youth political pressure, aid reduction, and Africa’s future trajectory

Studwell argues that Africa is now “in the game,” but success will depend on policy choices, institutional capacity, and political leadership.

In Episode 80 of the Charter Cities Podcast, Mark Lutter speaks with James of Ârc about building a global city that attracts ambitious people from around the world. James shares Arc’s long-term vision for city building and explains why talent, culture, and community are just as important as infrastructure and capital. They discuss how Arc is building momentum through pop-up cities and partnerships, creating a network of people who are ready to move when the opportunity arises. The conversation explores how new cities can compete with existing global hubs by offering strong governance, economic opportunity, and a high quality of life. They also discuss working with host nations, financing large-scale urban development, and why demonstrating new models of governance and city building may ultimately have the biggest impact beyond the city itself.

In Episode 79, Mark Lutter sits down with serial AI founder and investor Bradford Cross, now CEO of Alpha Cities, to explore what happens when a Silicon Valley systems thinker takes on the world’s most complex product: government.

Bradford argues that government should be treated as a product—one that often performs poorly, iterates slowly, and lacks the discipline of customer-centric design. Drawing from two decades of building and exiting AI companies (including powering LinkedIn’s newsfeed, deploying AI in big banks, and pioneering early machine-learning startups), he explains why governance is the ultimate systems challenge.

They dig into how the Silicon Valley playbook must be adapted—not imported—to work with sovereign states; why autonomy without integration (as seen in Honduras’ ZEDEs) is a dead end; how Alpha Cities structures zone laws, joint ventures, and regulatory sandboxes; and why the capital stack for new cities must move from friendly tech capital → industry anchors → sovereign wealth.

Bradford also shares a candid look at the overwhelming operational reality of building cities from scratch—and why the US should view charter cities as the private-sector alternative to China’s Belt and Road.

In this episode, Mark speaks with Rodney Lockwood, author of Belle Isle: Detroit’s Game Changer. Lockwood outlines his vision for turning Detroit’s Belle Isle into a privately funded “Freedom City,” inspired by models from Monaco, Singapore, Liechtenstein, and Switzerland. From governance reforms and land-value taxation to Formula One racing and monorail transport, Lockwood explains how bold experimentation could revitalize Detroit and demonstrate a new model for urban growth.

Grand Bahama’s Freeport is often left out of the origin story of special economic zones—but it shouldn’t be. In this episode, Mark sits down with Dillon F. Knowles, President of the Grand Bahama Chamber of Commerce, to trace Freeport’s beginnings under the 1955 Hawksbill Creek Agreement—arguably the first modern free trade zone—through its Vegas-on-the-Atlantic heyday and the slowdown that followed the 1967 “bend or break” speech.

Knowles explains how a city master-planned for 300,000 people (on an island nearly 2× the size of Singapore) ended up with ~40–50k residents, why tourism shifted from high-rollers to cruise lines, how hurricanes and policy ambiguity compounded the challenge, and why legal certainty plus investor-government alignment could unlock a renaissance. We cover today’s flashpoints (e.g., the $350M tax shortfall claim and arbitration), outline pragmatic reforms to “modernize Hawksbill,” and sketch a credible growth thesis for Freeport—spanning ports, hospitality, residential, and high-skill jobs.

If you care about zones, governance, and city-building, this is a case study you can’t miss.

In this conversation, Joel Burke and Carl Peterson discuss the remarkable transformation of Estonia into a leader in digital governance. They explore Estonia's journey from post-Soviet struggles to becoming a hub for tech innovation, including the rise of companies like Skype. Joel shares insights on Estonia's e-governance initiatives, the e-residency program, and the importance of cybersecurity following the Web War I incident. The discussion also highlights lessons learned for other nations and the inspiration behind Joel's book, 'Rebooting a Nation.'

In this Freedom Cities episode, Professor Tom W. Bell dives deep into the world of legal innovation and special jurisdictions. A law professor turned legal systems designer, Tom shares his journey from academia to advising real-world projects like the Catawba Digital Economic Zone and Free Society’s forthcoming decentralized city. He explains Ulex—his open-source legal system—and walks us through his proposed “Freedom Cities Act,” a bold legislative framework that could turn underutilized federal lands into hubs of regulatory experimentation and economic vitality. It’s a masterclass in freedom, law, and possibility.

In Episode 75 of the Charter Cities Podcast, we’re joined by Jarrad Hope—founder of the Logos Network and author of Farewell to Westphalia—to explore the provocative idea of post-nation-state governance. Jarrad and Mark dive into the decline of traditional state power, how blockchain technologies enable new forms of sovereignty, and why decentralized communities may soon provide public goods and governance systems once thought exclusive to the state. From smart contracts to off-chain political dynamics, this episode is a deep dive into the unbundling of governance and the frontier of crypto-sovereignty.

In Episode 7 of the Freedom Cities Podcast, Mark Lutter sits down with Alex Voss, CFO of Tipolis, a company pioneering the development of new cities around the world based on private governance models. Alex shares his journey from investment banking to building freedom-enhancing urban communities and dives into the evolving global landscape for charter and free cities. From Tipolis’ new project in Brunei to the potential of Freedom Cities legislation in the U.S., this conversation offers a deep look at how private cities are transforming economic development and governance. Alex also highlights the growing investor interest in this space and why well-designed cities are just as important as regulatory innovation.
